Q1A patient with type 2 diabetes shares with their healthcare provider that they want to make dietary changes to improve their diabetes management. Which of the following responses is BEST?
✓ Correct answer: D. "That sounds like a great approach! What kind of dietary changes are you considering, and how can I assist you in planning?"
Answer: "That sounds like a great approach! What kind of dietary changes are you considering, and how can I assist you in planning?" Balanced meals with mindful carbohydrate monitoring can help manage diabetes. The healthcare provider should support the patient in planning dietary changes, not enforce restrictive or trendy diets.
Q2A 68-year-old female client with advanced chronic kidney disease (CKD) stage 4, peripheral neuropathy, and type 2 diabetes presents to the clinic for a follow-up. She is currently on insulin therapy and her A1C is 8.5%. The healthcare provider knows:
✓ Correct answer: C. The client's A1C level is currently at goal
Answer: This client's A1C level is currently at goal. The goals of glucose control should be individualized based on the client's overall health status, particularly the presence of comorbidities, cognitive function, and ability to perform day-to-day activities. In clients with significant comorbidities such as advanced CKD, an A1C goal of > 8% might be appropriate to avoid hypoglycemia and other complications. This client fits those criteria making her current A1C of 8.5% acceptable. In the absence of significant comorbidities or functional decline, the A1C target may be more stringent (e.g., < 7%), but in clients with conditions like CKD, looser targets are often justified.
Q3The dietitian is discussing with a client why the endocrinologist has recommended adding a GLP-1 agonist to their current metformin therapy. The dietitian knows:
✓ Correct answer: B. Both postprandial and fasting glucose levels are generally elevated in most individuals with type 2 diabetes
Answer: Both postprandial and fasting glucose levels are generally elevated in most individuals with type 2 diabetes. Both overnight and between-meal glucose levels (fasting or basal) and the increments above pre-meal levels (postprandial) are increased in most people with diabetes, and both components of hyperglycemia typically worsen with increasing duration of diabetes. Both components, basal and postprandial, worsen with the increasing duration of diabetes. Metformin acts mainly on fasting and between-meal hyperglycemia, not on postprandial hyperglycemia. The addition of a GLP-1 agonist can help to improve glycemic control by addressing both postprandial and fasting glucose levels.
Q4Patients with diabetes need to be aware of specific symptoms that indicate complications from long-term high blood glucose levels. Which of the following symptoms suggests diabetic neuropathy?
✓ Correct answer: A. Numbness, tingling, and burning sensation in the feet
Answer: Numbness, tingling, and burning sensation in the feet. Diabetic neuropathy is a type of nerve damage that can occur with diabetes. Common signs include numbness, tingling, and a burning sensation, especially in the feet and hands. These symptoms result from prolonged high blood glucose levels, which can damage nerves over time. Symptoms like chest pain, shortness of breath, and dizziness are more indicative of cardiovascular problems, while frequent urination, thirst, and blurry vision are classic symptoms of high blood glucose levels. Weight loss, fatigue, and dry mouth are general symptoms that can be linked to various conditions but not specifically to diabetic neuropathy.
Q5A Certified Diabetes Care and Education Specialist is discussing healthy eating habits with a patient newly diagnosed with type 2 diabetes. Which of the following statements made by the patient indicates that further education is needed regarding the nutritional content of beverages?
✓ Correct answer: D. "I drink diet soda throughout the day because it has no sugar and will help me manage my weight better than water."
Answer: "I drink diet soda throughout the day because it has no sugar and will help me manage my weight better than water." While diet sodas do not contain sugar and have fewer calories than regular sodas, they contain artificial sweeteners and other chemicals that may still impact health negatively. Water is a better choice for staying hydrated without added chemicals. It's important to educate patients that moderation is key and that water should be the primary beverage for hydration. Regular consumption of diet sodas has been associated with other health risks and may not support overall health or weight management goals effectively. Healthier options like water, herbal teas, or sparkling water without added sugars or artificial sweeteners are preferable.
Q6An educator is conducting a session for individuals with diabetes who are considering various forms of exercise. Which of the following statements regarding exercise and diabetes management is NOT correct?
✓ Correct answer: C. High-intensity interval training (HIIT) is not recommended for individuals with type 1 diabetes.
Answer: High-intensity interval training (HIIT) is not recommended for individuals with type 1 diabetes High-intensity interval training (HIIT) can be safe and beneficial for individuals with type 1 diabetes, provided they have good glycemic control and are supervised by healthcare professionals. Regular physical activity improves insulin sensitivity, and monitoring blood glucose levels around exercise sessions helps manage diabetes effectively. Additionally, adjusting carbohydrate intake can prevent hypoglycemia during prolonged activities.
Q7A health educator is evaluating a lifestyle intervention plan for a patient with prediabetes. Which of the following statements is accurate?
✓ Correct answer: B. Engaging in a structured lifestyle intervention with the appropriate supports can significantly reduce the risk of progression to type 2 diabetes.
Answer: Engaging in a structured lifestyle intervention with the appropriate supports can significantly reduce the risk of progression to type 2 diabetes. Research shows that structured lifestyle interventions with proper support systems can greatly reduce the risk of developing type 2 diabetes in individuals with prediabetes. These interventions improve adherence, self-efficacy, and long-term behavior change. Minimal intervention and lack of structure are less effective in achieving and maintaining these results.
Q8A 45-year-old male with type 2 diabetes is experiencing persistent symptoms of anxiety. Which of the following is the MOST likely to be successful in treating the patient's anxiety?
✓ Correct answer: A. Cognitive behavioral therapy
Answer: Cognitive behavioral therapy Cognitive behavioral therapy (CBT) is widely recognized as an effective treatment for anxiety disorders in adults. Both CBT and mindfulness-based therapy are successful in managing anxiety symptoms. Antianxiety medication can be effective for severe anxiety disorders, particularly when combined with CBT. Interpersonal therapy is more traditionally used for depressive disorders, especially in adolescents. Motivational interviewing is primarily applied to improve motivation and commitment to behavioral changes and not specifically for treating anxiety.
Q9Which of the following statements about neuropathy in people with diabetes is TRUE?
✓ Correct answer: D. Neuropathy is more common in people with diabetes and can develop at an earlier age than in people without diabetes.
Neuropathy is more common in people with diabetes and can develop at an earlier age than in people without diabetes. High blood glucose levels can cause nerve damage over time, leading to diabetic neuropathy. It is not directly linked to cholesterol levels, risk of cardiovascular events, or surgical treatments of foot ulcers.
Q10A patient with type 2 diabetes is hospitalized and placed on an insulin regimen that includes a low dose correction insulin scale. Prior to lunch, the patient’s blood glucose reading is 175 mg/dL. How many units of rapid-acting insulin should the nurse administer?
✓ Correct answer: C. 2 units
Answer: 2 units Using the low dose correction insulin scale, for a blood glucose level of 175 mg/dL, 2 units of rapid-acting insulin are to be administered. On the low dose correction insulin scale, 1 unit of rapid-acting insulin is given for blood glucose levels between 140-160 mg/dL, and 4 units are given for levels between 180-200 mg/dL. Rechecking the blood glucose without administering insulin isn't appropriate as the blood glucose level of 175 mg/dL requires intervention based on the low dose correction insulin scale.
